If you want to join the two ends of a tube together you need to use a broomstick and vulcanizing fluid. You put the end of the broomstick alongside the tube a couple of inches back from the end of the tube opening and then pull the tube back over itself onto the broomstick. Then you fold it back on itself in a one inch cuff. You then take the other end of the tube and pull it over the end of the broomstick and up to the cuff you have formed. Then you put vulcanizing fluid on half inch of the end of the tube and on half inch of cuff. Let that dry completely (like contact cement) and then roll the cuff over top of the end of the tube. Hard to explain but it will make more sense when you try to do it.
